About This Design
Math geek Pi symbol, blue on black Key Ring
It you would like to get the design where the first 10,000 numbers of Pi are clearly visible, I also have that design, with a few variations, on my store. Pi is an irrational number, that is calculated by dividing the circumference of a circle by its diameter. Nothing seems so simple, yet Pi is one of the most fascinating, non-repeating numbers (at least for now) ever. Show of your love for mathematics with this design, full of geeky attitude.

Beyond expectations. Choice of artwork is overwhelming, I found exactly what I needed from SJW_Graphics. Detail, colors, overall design looks great on this keyring. Could use as a pendant, purse charm, bookmark, too! Metal is sturdy without being heavy. Colors beautiful, with clear margins. Customized name makes this gift extra special. So many fonts, so many colors & sizes!
